Preparing for sales, Black Friday and the holidays

23 August 2026 · 8 min read · By the Dresskool team

A year selling secondhand isn't a smooth path. It's made up of four peaks and several valleys, and the difference between an ordinary week and a peak week can triple your sales on the same inventory, without you changing anything in your listings.

The catch is that these peaks need six to eight weeks of preparation. Sellers who discover Black Friday on the Wednesday before spend the week scrambling, while those who planned ahead cash in. Here's how to organize by window.

What a peak actually changes

A sales peak doesn't just increase your number of orders. It changes three things at once, and their combination overwhelms unprepared sellers.

First, messages explode before sales do. Buyers ask questions, request measurements, negotiate, place holds. Expect two to three times the messages you'd get in a quiet week, and many won't turn into purchases.

Second, logistics gets stretched. Pickup points become congested, collection times lengthen, and a parcel dropped Friday evening might not get scanned until Tuesday. A buyer who paid for a Christmas gift on 15 December won't understand that delay, and you'll be the one getting the bad review.

Third, competition rises too. Everyone publishes at the same time, which pushes your listings lower in results and makes fresh listings more decisive than usual.

The four windows of the year

Back-to-school: late August and September

This is the most underestimated window. Demand picks up sharply after the August slump, on three specific segments: children's clothes that no longer fit, work wardrobes for people returning to jobs, and the first mid-season pieces.

Its advantage is low competition: many sellers come back slowly from holidays. A serious relist in late August captures real demand with few competitors.

Black Friday: the last week of November

This is the most intense and shortest peak. In practice it runs from the Monday before through the Monday after, with the spike hitting Friday and the weekend. Buyers arrive with purchase intent already formed and a mental budget set.

On secondhand the effect is less dramatic than on new goods, but real, especially on mid-value pieces: coats, bags, shoes, recognizable brands. It's also when buyers compare most, so a poorly filled-out listing loses to a complete one at the same price.

The holidays: early December until the 18th

The gift-giving window closes sooner than people think. After 18 December, a buyer ordering to give as a gift takes a delivery risk she won't assume: orders collapse abruptly several days before Christmas.

What sells here isn't what sells the rest of the year. Accessories, brand-new tagged pieces, well-presented branded items and anything gift-worthy outrank basics.

Winter sales: January

Contrary to popular belief, January isn't dead for secondhand. It's different. Buyers have spent, they're hunting deals, and they're also clearing their wardrobes, which makes it an excellent sourcing month for you.

Average order value drops, but volume holds. It's the right time to clear what didn't move in autumn rather than leaving it dormant until spring.

The six-week rule. A piece needs to be live six weeks before the peak you want to target it at. A down jacket published 20 November for Black Friday arrives too late: it won't have had time to be seen, favourited and compared. Publish end of October and let the peak work its magic on already-established listings.

Preparing your inventory before the peak

Preparation depends on three lists, to be made once before each window.

The first is pieces to bring out. Everything that fits the coming season needs to come out of storage, be checked, washed if needed and photographed. Don't do this piecemeal during the peak: you won't have time.

The second is existing listings to refresh. Those that have been sitting for weeks deserve new main photos, revised titles and republishing. Our article on republishing and the algorithm explains the order to do this so it counts.

The third is supplies. Padded envelopes, boxes, tape, labels, tissue paper. Running out of envelopes on Black Friday weekend costs you two days of shipping, and no one thinks to count stock before they're out.

If you work with consignors, alert them six weeks ahead: it's time to collect their winter pieces, not 15 December. Our guide to seasonality in secondhand selling details the full collection calendar.

Pricing during a peak: the classic mistake

The most common mistake is slashing prices because it's Black Friday. It's a reflex borrowed from new goods, where a retailer needs to move inventory they paid for before stocktake. Your situation is different.

In secondhand, the peak brings extra traffic on unique pieces. Cutting prices thirty percent when demand rises means sacrificing margin on sales you'd make anyway. The right approach is more nuanced.

On recent, desirable pieces, hold your prices: they'll sell. On pieces sitting for two months or longer, cut sharply, because the peak is your best chance to move them before season end. On bundles, offer a volume discount rather than per-item discounts: this protects your listed prices while giving a reason to buy multiples.

Logistics: the real bottleneck

During a peak week, it's almost never sales that jam up, it's shipping. Three decisions made in advance prevent gridlock.

Choose fixed drop-off times instead of going whenever: two drop-offs a week at set times beats six improvised trips. Batch-pack your parcels in a clear space with everything within reach. And identify a backup drop-off point, because yours will be swamped at least once.

Tell your buyers too. A line in your description stating your shipping days prevents half the worried messages and most of the poor reviews tied to delays. Our article on sending parcels covers packing best practices and proof of drop-off.

For those managing dozens of listings, the repetitive work of publishing, republishing and tracking orders can be handled by a dedicated tool like DressKare, which frees the hours that are most precious during these weeks.

After the peak: don't miss January

The week after a peak is when people let everything slide, and that's a mistake. Three quick steps are worth the effort.

Count what sold and what didn't, by category. This is the only info that will tell you what to source next year, and it's forgotten in two weeks if you don't write it down.

Handle returns and disputes straight away rather than letting them pile up: a dispute opened over the holidays settles much better in early January than in February.

Finally, relist your unsold items with adjusted prices without waiting. They'll benefit from January traffic, which is real even though the average order value is lower. Our article on cash flow and dormant stock explains why letting a piece sit costs more than selling it cheaper.

The calendar to note right now

Remember four prep dates and build the rest around them. Mid-July for back-to-school. Mid-October for Black Friday. Early November for the holidays. Early December for January.

Each of these dates means the same thing: pull stock, refresh listings, alert consignors, check supplies. It's not complicated, it's just easy to forget when you're busy.

A well-run year selling secondhand doesn't ask you to work more. It asks you to work at the right times.

Frequently asked questions

Do you really need to lower prices during Black Friday?

Not on everything. In secondhand, you're selling unique pieces and the peak mainly brings you extra traffic: cutting prices on recent, desirable items means losing margin on sales you'd make anyway. Reserve steep discounts for pieces that have been sitting for two months or longer, where the peak is your best chance to clear them before season end.

When should you list your winter pieces?

Six weeks before the peak you're targeting: end of October for Black Friday, early November for the holidays. A listing needs time to be seen, favourited and compared. Publishing a down jacket on 20 November hoping for Black Friday means arriving too late: the piece will have had no exposure before the critical moment.

What's the last date to sell for Christmas?

Practically, 18 December. After that, a buyer ordering to give as a gift takes a delivery risk she won't accept: orders drop sharply several days before Christmas. If you want to capture the end of the period, push gift cards or local pickup instead of shipping.

How do you avoid poor reviews due to delivery delays?

State your shipping days directly in your descriptions and stick to them. Most poor reviews at year end don't come from actual delays but from unmanaged expectations: a buyer who's told a parcel ships Tuesday waits patiently; a buyer who knows nothing worries the next day. Also identify a backup drop-off point, because yours will be overwhelmed at least once.

Is January dead for secondhand?

No, it's just different. Average order value drops but volume holds, because buyers are hunting deals after spending. It's also the best month of the year to source, since many people clear their wardrobes then. Relist your unsold items with adjusted prices in the first week rather than waiting for spring.
